Melowilo Graph Editor Toolkit - Blender Addon

Melowilo Graph Editor Toolkit

A Blender addon that provides a collection of essential channel visibility and batch keyframe editing tools directly in the Graph Editor's sidebar. It is designed to streamline the animation workflow by offering quick access to common but repetitive tasks.

Key Features

The toolkit is conveniently located in the Graph Editor Sidebar (`N` Panel) -> "Key Tools" tab.

Channel Management

- Hide Others: Instantly hide all channels except for the ones you have selected.

- Unhide All: Reveal all hidden channels in the current view.

Batch Keyframe Editing

Quickly modify properties for all selected keyframes at once.

> Note: All editing operations intelligently apply only to keyframes on F-Curves that are also selected in the channel list. This prevents accidental changes to hidden or unselected channels.

- Set Interpolation: Change the interpolation mode for selected keys with a single click (Constant, Linear, Bezier, Back, Bounce, Elastic).

- Set Handle Type: Set the handle type for selected keys (Free, Aligned, Vector, Auto, Auto-Clamped).

- Set Absolute Value & Frame:

- Apply Value: Set the value (`Y-axis`) of all selected keyframes to a specific number.

- Apply Frame: Move all selected keyframes to a specific frame (`X-axis`).

- Offset Value & Time:

- Offset Value: Add or subtract a specific amount from the value of selected keyframes.

- Offset Time: Add or subtract a specific amount from the frame of selected keyframes.

Utility Tools

- Selected Key Info: A display that shows the Frame and Value of your selection. If multiple keys are selected, it shows their average value.

- Copy/Paste Value: Copy the value from a single selected key and paste it onto one or more other selected keys.

- Insert Keyframe: Inserts a new keyframe on all selected channels at the current timeline frame.

- Toggle Handles: A convenient button to show or hide the Bézier handles for all curves in the Graph Editor.
